About this study

This human laboratory study will use cognitive, behavioral, and subjective measures to characterize impairment associated with co-use of alcohol and vaporized cannabis. Participants (n=32) will complete 7 double-blind, double-dummy outpatient sessions in randomized order. In each session, participants will self-administer placebo (0 mg THC) or active vaporized cannabis (5 or 25 mg THC, via a handheld vaporizer called the Mighty Medic) and a placebo drink (BAC 0.0%) or alcohol drink calculated to produce a breath alcohol concentration (BAC) of 0.05%. Participants will also complete a positive control session in which the participant administers placebo cannabis and alcohol at a target BAC of 0.08% (the legal threshold for driving impairment in most U.S. states).
